4 Frequently Asked Questions about “UK Energy Storage in 2025 - ID Solar Energy Systems”
How many solar installations are there in the UK in May 2025?
There were 21,125 small-scale solar installations in the United Kingdom in May 2025, according to accreditation body MCS, which also recorded a record month for battery energy storage additions. Data for PV installations up to 50 kW show May's installation figures were 30% higher than the same month the previous year.
Are battery energy storage systems the UK's future?
The UK's energy landscape is undergoing an unprecedented transformation, with renewables supplying ever-more of our electricity and demand for electricity growing, which means an increased need for flexible storage assets like battery energy storage systems (BESS). But what battery assets does the UK boast currently?
How much battery storage capacity has been commissioned in 2025?
In 2025 to date, approximately 1,405MW of new battery storage capacity has been commissioned, already surpassing the 2024 total of 1,249MW. According to EnergyPulse's research there is approximately 6.5GW of capacity currently under construction and over 60GW of capacity currently consented.
How is the UK's solar energy and battery storage sector changing?
The UK's solar energy and battery storage sector is undergoing a rapid transformation, bolstered by ambitious climate targets and supportive policies. Solar photovoltaics (PV) capacity has rebounded since the end of feed-in tariffs, while energy storage is scaling up to enhance grid reliability.
